D because 5 times 2 is 10 and - cuts off - so -3 times -3 would be 9 so 10+9 is 19 :)
Idk I just want points can u give breanlyist please
Same . It’s not giving me a lot of information!!
(2x+1)=Jeremy´s age
(2x+3)=Sam´s age.
we suggest this equation:
(2x+1)(2x+3)=783
4x²+6x+2x+3=783
4x²+8x-780=0
x²+2x-195=0
We solve this quadratic equation:
x=[-2⁺₋√(4-4*1*(-195))]/2=(-2⁺₋28)/2
x₁=(-2-28)/2=-15 this solution is not valid.
x₂=(-2+28)/2=13
Jeremy´s age=2x+1=2*13+1=27
Sam´s age=2x+3=2*13+3=29
Hey there!
5 x w = 10 to the second power . . .
10 x 10 = 100
5 x 100 = 500
5 x w = 500
500 = 5w
w = 100 <-------
Hope this helps you.
Have a great day!
